Chapter 1 Basic Router Configuration

Configuring Enhanced IGRP

 

Command

Purpose

Step 2

 

 

network ip-address

Specifies a list of networks on which EIGRP is to

 

 

be applied, using the IP address of the network of

 

Example:

directly connected networks.

 

Router(config)# network 192.145.1.0

 

 

Router(config)# network 10.10.12.115

 

 

Router(config)#

 

Step 3

 

 

end

Exits router configuration mode, and enters

 

 

privileged EXEC mode.

 

Example:

 

 

Router(config-router)# end

 

 

Router#

 

 

 

 

For complete information on the IP EIGRP commands, see the Cisco IOS Release 12.3 documentation set. For more general information on EIGRP concepts, see Appendix B, “Concepts.”

Configuration Example

The following configuration example shows the EIGRP routing protocol enabled in IP networks 192.145.1.0 and 10.10.12.115. The EIGRP autonomous system number is assigned as 109.

Execute the show running-configcommand from privileged EXEC mode to see this configuration.

Verifying Your Configuration

To verify that you have properly configured IP EIGRP, enter the show ip route command, and look for EIGRP routes indicated by “D.” You should see verification output similar to the following example.
